'lhe invention disclosed in this application relates to window channel especially adapted for the windows of automotive vehicles.

ln applying window channel to window grooves it is diiiicult, with the loody makers on the one hand and the channel makers on the other, to produce a proper l tit hetween the walls of the groove and the channel laterally and it is well to provide for lateral yield without unduly afecting the side flanges and their proper engagement with the'glass pane.

W ith the foregoing in mind, this invention contemplates providing the hase of the channel with an upwardly extending 'l-shaped projection which not only acts as a spacer for the glass but provides a collapsible yielding structure at the center of the base oi the channel so that the channel may give transversely through the hase to permit the application of the channel to varying window grooves without affecting the predetermined tension upon the side flanges and their predetermined grip upon the glassa The invention is very well disclosed in the following description, drawing and claims.

ln the drawing, Fig. l shows a piece of channel; and Fig. 2 shows a cross section thereof.

ln the embodiment shown9 the channel is preferably made up of a thin sheet steel core comprising a hase l and side iianges 2 hent at right angles thereto and curved inwardly to engage the glass.

'lhe hase is provided with an upwardly eru tending V-shaped memher 3 which9 in the structure., has sucient lateral tension to hold the outer corners of the hase in the hase of the ieee. serial no. essere.

flat bottom portions and side anges heut at substantially right angl-es thereto and curved inwardly to form glass engaging portions near their outer edges, and a suitable flute formed in the base for permitting lateral yield of the channel to adapt it to varying outer di mensions olf window grooves.

2. Window channel as in claim l wherein the flute is formed by a V-shaped projection extending inwardly into the channel.
